Application filed February 3, 1914. Serial No. 816,270.

To all whom it may concern.

Be it known that I, CLIFTON T. DODSON, a citizen of the United. States, residing at W'hitney, in the county of Hill, State of Texas, have invented certain new and useful Improvements in Money- Changing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to money changing machines.

The object of the invention resides in the provision of a machine of the character named which embodies improved mechanism manually operable after a coin of given value has been deposited in the machine to effect the discharge of a number of coins from the machine having an aggregate value equal to the coin deposited.

A further object of'the invention resides in the provision of a machine of this character which includes means automatically operated when the coins in the magazine of the machine have been reduced in quantity a predetermined extent to prevent the insertion of coins to be changed into the machine.

A still further object of the invention resides in the provision of a machine of the character named which will be simple in construction, efiicient and reliable in use, and in which the sizes and proportion of the various parts may be readily carried to enable the machine to be used in connection With coins of various denominations.

lVith the above and other objects in view the invention consists in the details of con struction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of refer ence denote corresponding parts in the several views, and in which Figure '1 is a side elevation of a money changing machine constructed in accordance with the invention, the near side of the easing of the machine being removed; Fig. 2, a section on the line 2-2 of Fig. 1; Fig. 3, a section on the line 33 of Fig. 2 with the parts in the position they would occupy when the plunger of the machine has been operated to a position to effect the discharge of a predetermined number of coins from the machine; Fig. .t, a section on the line 41 of Fig. 2; Fig. 5, a view similar to Fig. 4: showing the position of the parts after a coin to be changed has been deposited in the machine and before the. plunger of the machine has been operated; Fig. (3, a fragment of what is shown in Fig. 5 with the parts in the position they would occupy after the plunger has been fully operated to effect discharge of coins from the machine in exchange for the coin previously deposited; Fig. 7, a detail perspective view of the pivoted locking plate of the machine; Fig.

8, a detail perspective view of the plunger of the machine; Fig. 9, a detail perspective view of the weighted shutter lever, and Fig. 10, a section on the line 10*10 of Fig. 1.

Referring to the drawings the machine is shown as comprising a casing A which includes front and rear members 15 and 16 respectively, side members 17 and 18-, and top and bottom members 19 and 20 respectively. Rising from the bottom member 20 is a vertical partition 21 the upper end of which is secured to a horizontal partition 22 which has one end supported by the front member 15. The vertical partition 21 is provided with an opening 23, while the front member 15 is provided with an opening 24 disposed between the horizontal partition 22 and the bottom 20. Connecting the front and rear members 15 and 16 is a plate 25 disposed above and in parallel spaced relation to'the partition 22, said plate being connected to the latter by spaced vertical members 26. The plate 25 is provided adjacent the rear member 16 with an opening 27 and chute 28 supported between the vertical partition 21 and the plate 25 has its upper end in communication with the opening 27 and its lower end in communication with the opening 23. Mounted upon the plate 25 is a guide block '29 in which is slidably disposed the stem 30 of a plunger 31, said plunger being provided w1th an opemng 32 of a diameter to enable said opening to snugly recelve the coins to be discharged from the machine as will hereinafter appear. This opening 32, when the plunger 31 is in its normal or retracted position lies over an opening 33 formed in the plate 25 just forward of the opening 27. The stem 30 of the plunger 31 a is provided with a lateral extension 33 directed toward the side wall 18 and normally held in engagement with the inner side of the front wall 15 by means of a leaf spring 34 mounted on a plate 35 which is secured againstthe inner side of the front wall 15. The stem 30 beyond the extension 33 is enlarged and, slidably engaged through the front wall 15 as at 36. Disposed above the plate r25 and having one end supported by the guide block 21) and its other end secured to the reafmember 16 is a plate 37 and engaged through this plate is the lower end of a coin tube 38, the upper end of said tube being engaged through the top 19 of the casing. The top of the tube 38 is adapted to be closed by a door or cover 39 hinged to the top 19 and adapted to be secured against movement to open position by means of a lock 40.

The front wall 15 is provided with a coin inserting slot 41 adjacent its upper end and slidably disposed against the inner side of the front wall is a shutter 42 provided with a slot 43 adapted in one position of the shutter to register with the slot 41. The upper end of the shutter 42 is provided with a reduced extension 44 which is slidably engaged in a guide block 45 carried by the front wall 15. The lower end of the shutter 42 is likewise provided with a reduced extension 46 which is slidably engaged in a guide member 47 carried by the front wall 15. Pivoted between the members 26 is a shutter controlling lever 48 one end of which has pivotally connected thereto an of the lever 48 adjacent the ,front member 15 is weighted and provided with a lateral extension 50 directed toward the side wall 18. Pivotally connected to this extension 50 is one end of a link 51, the other end of said link being pivotally connected to the lower end of the extension 46 of the shutter 42. By this construction it will be apparent that when the coins deposited in the tube 38 are of sufficient aggregate weight to force the rear end of the lever 48 downwardly the shutter 42 will be elevated and in this position of the shutter the slot 43 will register with the slot 41 so that insertion of a coin to be changed through the slot 41 and into the machine is rendered possible. As soon as a suflicient number of coins have been re moved from the tube 38 to reduce the aggregate weight of. the coins remaining to less than the weight on the front end of the lever 48 it will be apparent that the front end of said lever will move downwardly and draw the shutter 42 with it. The slot 43 will thus be. moved out of registration with the slot 41 and insertion of a coin through theslot 41 will be impossible until the tube 38 is recharged with coins. 4

Mounted upon the side wall 18 is a coin chute 52 the bore of which at its upper end is disposed in line with the slot 41 and of course with the slot 43 when the shutter 42 is elevated. The bottom of the chute 52 is provided with an opening through which coins of a less size than those intended to be inserted in the machine can freely pass. Carried by the chute 52 and disposed in opposite inclination to the latter is a chute 54 which is adapted to receive the coin discharged through the opening 53 and convey them forwardly of the machine into a slot 55 in the front wall of the machine from whence they are discharged to the exterior. Secured to the bottom of the chute 52 is a block 56 having a lateral extension 57 at its outer end. This extension 5'7 is in line with an opening 58 formed in the bottom of the chute 52 and carries a pin 59 extending transversely thereth'rough and projecting at one end into the opening 58. In the event a washer or similar article having the same diameter as the coin designed to be inserted in the machine is utilized. in lieu of such coin the same will drop through the opening 58 and engage around the pin 59 from which it can be remov ed at pleasure. It will thus be seen that the machine cannot be operated by using coins of less diameter or articles having a central opening and the same diameter as the coin intended to be used in connection with the machine. Pivoted between the plate 25 and the side member 18 is a locking plate 60 provided at one end with a locking flange 61 adapted to en gage the lateral extension 33 when the plate 60 is disposed in normal or horizontal position, said plate being held in such position by a weight 62 secured thereto. By this construction it will be apparent that when the plate 60 is disposed in horizontal position it will be impossible to move the plunger 31 toward the rear wall 16. The end of the plate 60 adjacent the rear member 16 is provided with a longitudinal flange 63 from which projects laterally an arm 64 disposed over and in parallel relation to the plate 60. Mounted upon the plate 60 is a leaf spring 65 for a purpose that will presently appear. Secured to the rear member 16 of the casing against the inner face thereof is a block 66 having a curved face 67 which is adapted to be traversed by the adjacent end of the plate 60 during the pivotal movement of said plate. Supported by the casing A. at the lower end of the latter is a casing B which is connected to the interior of the casing A by a chute 68.

Assuming the parts to be in the position i shown in Fig. 1 and that the machine is adapted to exchange one cent coins for five cent coins it will be apparent that when the five cent coin is inserted in the slot 41 it will pass through the coin chute 52- and be 1-- discharged upon the end of the locking plate 60 adjacent the rear member 16 of the casin A. The weight of the coin upon the plate 60 will depress the rear end of the plate until the leaf spring 65 engages a stop 69 carried by the block 56. This position of the plate 60 is clearly illustrated in Fig. 5, the coin being disposed in engagement with the lower end of the curved face 67 When the plate 60 is in the position shown in Fig. 5 it will be obvious that the flange 61 is moved out of engagement with the lateral extension 33, leaving the plunger 31 free to be pressed toward the rear member 16 against the influence of the leaf spring 34. The thickness of the plunger 31 is equal to the combined thickness of five one cent coins and it will therefore follow that when the plunger 31 is moved toward the rear member 16 it will carry with it five one cent coins disposed in the opening 32. During the movement of the plunger 31 toward the rear member 16 the opening 32 will register with the opening 27 and the coins carried by the plunger will drop through the opening 27 into the chute 28 from whence they will be discharged upon the bottom 20 forward of the partition 21. It will be noted that during the movement of the plunger 31 toward the rear member 16 the lateral extension 33 will engage the locking plate 60 and move same to the position shown in Fig. 6 against the influence of the spring 65 with the result that the coin carried by the plate 60 will be discharged into the chute 68 and thence into the casing B. Upon the plunger being released the various parts will return to the position shown in Fig. 1.

It will be notedthat the casing B may be provided with a suitable door and lock whereby access thereto for the removal of the coins may be had.

What is claimed is In a money changing machine, the combination of a casing having a slot therein for the insertion of a coin to be changed, a coin magazine, a shutter slidably mounted on the casing and provided with a slot adapted to register with the slot in the casing in one position of the shutter, a platform pivoted in the casing and having one end disposed beneath the magazine to receive the weight of the coins in said magazine, and connections between the shutter'and the other end of said platform whereby the pivotal movement of the platform will move the shutter, said shutter'being held in position to register the slot of the shutter with the coin slot in the casing by a predetermined weight of coins and movable under the influence of gravity to close the coin slot in the casing when the weight of the coins in the magazine has been reduced a predetermined extent.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
